Consolidated Container In the second quarter of 2017, Consolidated Container entered into a credit agreement providing for a $605 million term loan and a five year $125 million asset based lending facility (“ABL facility”) in conjunction with the acquisition discussed in Note 2. The term loan is a variable rate facility which bears interest at a floating rate equal to the London Interbank Offered Rate (“LIBOR”) plus an applicable margin of 3.5%, subject to a 1.0% floor. The term loan matures on May 22, 2024 and requires annual principal amortization of 1.0% of the original loan amount beginning December 31, 2017. Consolidated Container recorded approximately $19 million of debt issuance costs, which will be amortized over the terms of the facilities. Consolidated Container entered into interest rate swaps for a notional amount of $500 million to hedge its cash flow exposure to the variable rate debt. These swaps effectively fix the interest rate on the hedged portion of the term loan at approximately 5.6%. As of September 30, 2017, Consolidated Container had no borrowings outstanding under its ABL facility.
